[Bug 1355829] Re: rpc.mountd segfaults after upgrading to 1:1.2.8-8ubuntu1

[Launchpad Bug Tracker]

This bug was fixed in the package nfs-utils - 1:1.2.8-9ubuntu1

---------------
nfs-utils (1:1.2.8-9ubuntu1) utopic; urgency=medium

  * Merge from Debian usntable, remaining changes:
    - debian/nfs-common.{statd,statd-mounting,gssd,idmapd}.upstart,
      debian/control, debian/nfs-common.{preinst,postinst,prerm,postrm},
      debian/rules: drop nfs-common init script in favor of upstart jobs.
    - Depend on rpcbind (>= 0.2.0-6ubuntu1) for upstart support.
    - Depend on mountall (>= 2.41) to avoid deadlocks on boot.
    - debian/nfs-common.default: always start idmapd automatically; drop
      the configuration option.
    - nfs-kernel-server.init: Unmount nfsd fs when init script stops
    - Allow issuing options to rpc.nfsd
    - Add "-e" (ticket expiry is error) option to rpc.gssd to prevent hangs
      due to EKEYEXPIRED error from kernel on ticket expiry.
    - drop nfs-kernel-server's LSB dependency on nfs-common.
    - Add patch to adjust for changes to the ctx argument of the
      serialize_krb5_ctx() function.

nfs-utils (1:1.2.8-9) unstable; urgency=medium

  * debian/patches/22-mountd-fix-segfault-in-add_name-with-newer-gcc-
    compi.patch: cherry-pick fix from upstream for a segfault in
    add_name with newer gcc compilers.  Closes: #757835, LP: #1355829.
